The framing is up. The materials were delivered. The work passed inspection.
And the check still hasn’t come.
For California contractors, subcontractors, and material suppliers, this is a familiar story. Construction runs on tight margins, and one unpaid project can put pressure on payroll, suppliers, and the next job.
California gives the construction industry a powerful tool for this situation: the mechanics lien. But it comes with strict deadlines, and missing one can cost you your rights.
What Is a Mechanics Lien?
A mechanics lien is a claim recorded against the real property where you provided labor, services, equipment, or materials. In simple terms, it ties your unpaid bill to the property you improved.
That matters because property owners usually want clear title. A recorded lien can affect an owner’s ability to sell or refinance, which often brings everyone back to the table.
The right to a lien comes from California law, and the rules are found in the California Civil Code. Those rules are technical, and they are enforced strictly.
Who Can Use a Mechanics Lien?
In general, the people who may be entitled to lien rights on a private California project include:
- Direct (prime) contractors who contract with the owner
- Subcontractors
- Material suppliers and equipment lessors
- Laborers
- Certain design professionals
Whether you qualify on a particular job depends on your role, your license status where one is required, and whether you took the right steps along the way.
Step One: The Preliminary Notice
For many claimants, lien rights start with a document sent at the beginning of the job, not the end.
Under California Civil Code section 8204, a preliminary notice generally must be given no later than 20 days after the claimant first furnishes work on the project. Subcontractors and suppliers who don’t contract directly with the owner usually need to send one. Direct contractors and laborers may have different requirements.
Sending the notice late does not always wipe out your rights, but it can limit your lien to work provided within the 20 days before the notice and afterward. That can be a costly reduction.
The lesson: send it early, send it correctly, and keep proof that you sent it.
Step Two: Recording the Lien on Time
The recording deadline depends on who you are and whether the owner recorded a notice of completion or cessation.
- Direct contractors generally must record after completing their contract and before the earlier of 90 days after completion of the work of improvement or 60 days after the owner records a notice of completion or cessation (Civil Code section 8412).
- Subcontractors, suppliers, and other claimants generally must record after they stop providing work and before the earlier of 90 days after completion or 30 days after a recorded notice of completion or cessation (Civil Code section 8414).
That 30-day window can close fast, especially if you don’t know a notice of completion was recorded.
Step Three: Enforcing the Lien
Recording is not the finish line. Under Civil Code section 8460, a lawsuit to enforce the lien generally must be filed within 90 days after the lien is recorded, unless a qualifying extension of credit is recorded. If that deadline passes, the lien expires and becomes unenforceable.
Many claimants record a lien and then wait, hoping it alone will force payment. Sometimes it does. When it doesn’t, the clock keeps running.
Attorney Insight
Attorney Insight: The most common lien problems we see are not about whether the work was done. They are about paperwork and timing: a missing preliminary notice, an incorrect property description, or a deadline calculated from the wrong date. A lien that isn’t prepared and timed correctly may not protect you, and an improper lien can create problems of its own. Have the documents reviewed before you record.
Example Scenario (Hypothetical)
The following is a hypothetical example for illustration only.
A Sacramento lumber supplier delivers framing materials to a commercial remodel through a subcontractor. The supplier sends a preliminary notice within a week of the first delivery. Months later, the subcontractor stops paying and owes about $62,000.
The supplier’s credit manager checks the county records and learns the owner recorded a notice of completion two weeks earlier. That leaves only days to record a lien. Working with counsel, the supplier records on time. Soon after, the owner and general contractor open payment discussions to clear the title.
Had the preliminary notice been skipped, or the recorded notice missed, the outcome could have been very different.
Other Tools Worth Knowing
A mechanics lien is not the only option. Depending on the project, a contractor or supplier may also consider:
- A stop payment notice, which targets construction funds held by the owner or lender
- A claim against a payment bond, common on public projects where liens generally aren’t available
- A standard breach of contract claim against the party that hired you
Often more than one of these can be used together.
Questions Contractors Ask Us
Do I need to send a preliminary notice if I contracted directly with the owner?
The requirements differ by role, and direct contractors are treated differently than subcontractors and suppliers. Because the rules have exceptions, confirm your obligations at the start of every project.
Can I file a mechanics lien on a public project?
Generally, no. Public property usually can’t be liened, but stop payment notices and payment bond claims may be available instead.
What if I missed the 20-day preliminary notice deadline?
You may still be able to send a late notice, though your lien rights may be limited to work provided within the 20 days before the notice and afterward. Talk to an attorney promptly.
Does recording a lien guarantee I’ll be paid?
No. A lien is a strong tool, but recovery depends on the property, the parties, and the facts. It works best when paired with a clear collection plan.
Protect Your Payment Before the Job Ends
In construction, your best collection work happens at the start of the job, not the end. Track your deadlines. Send your notices. Keep your paperwork tight.
You built it. You deserve to be paid for it.
